Coincidence theorems for finite topological spaces

Dynamical Systems 2020-10-27 v1 Algebraic Topology

Abstract

We adapt the definition of the Vietoris map to the framework of finite topological spaces and we prove some coincidence theorems. From them, we deduce a Lefschetz fixed point theorem for multivalued maps that improves recent results in the literature. Finally, it is given an application to the approximation of discrete dynamical systems in polyhedra.
